    PERRIN Turbo Inlet Hose Blue ( Part Number: PSP-INT-421BL)
    good stuff 1 year ago

    Ughh... But you need this thing so you don't ever have to do it again. Its not really that hard of an install with some wd-40. and about 3 hours. I'm not a mechanic but with the you tube video I pulled it off and it looks great. On a Legacy GT.

    I read all the reviews and pains people went through to install this tube. And although it's not an easy install it didn't seem as bad as I imagined. The hardest part was getting it to seat and stay on the turbo while clamping it. The instructions were pretty good and the quality is great. I installed this along with intercooler and I wish I didn't wait so long. Power seems to come on much quicker and at lower rpm.

    Great Product 3 years ago

    I bought this for my 2009 Subaru WRX. I did the install myself, it took a little longer than I anticipated. Getting the hoses to fit back on was kind of a PITA. Could notice the difference right away. A good buy if you have other supporting mods done.

    The install is definitely a pain but well worth it. I went with a larger turbo and this has kept my boost coming in at low rpm. Almost responsive as stock. Highly recommend.

    Excellent piece, took 2 hours to install, iv never done an inlet hose before so it wasn't to bad. The instruction were great easy to follow. The hardest part was hooking all the little hoses back up. I had to trim my Cobb sf intake hose to fit properly but other than that it was great , thanks rsd for a great product !!

    QUESTIONS & ANSWERS

    • Q: '12 WRX - 18g turbo  3 years ago

      will this fit a tomioka td05-18g turbo setup?
      • 1 of 1 people found the following answer helpful

        A:  We do not carry the Tomioka and could not confirm. As long as it uses a stock sized turbo inlet hose it should fit.

    • Q: Interference  pjkolosha4 years ago

      Will this turbo inlet interfere with the hard steering line? With the 08+wrx
      • 1 of 1 people found the following answer helpful

        A:  This is confirmed to fit with your vehicle without a problem. Perrin states in their instructions regarding the power steering line; Due to the PERRIN inlet hose being larger diameter than the OEM inlet hose, it may touch on the intake manifold and power steering pressure line. This is completely normal and nothing to worry about. The multi layer silicone hose is very resistant to abrasion type wear.
